How to Emulate Hover Interaction on Touchscreens
In the realm of web development, simulating hover effects on touch-enabled devices has been a lingering challenge. But fear not, for a clever solution exists that combines CSS and JavaScript to make it a breeze.
Imagine you have an element with some text and styles applied, including a hover effect that changes the font color. Let's say you want to extend this hover functionality to touch events on touch-screen devices. Here's how it's done:
Step 1: Adjust the CSS
Instead of using standard ":hover" selectors, we'll create a new CSS class called "hover_effect." This class will be responsible for applying the hover styles.
<code class="css">element:hover, element.hover_effect {
color: red;
}</code>
Step 2: Add Touch Event Listeners using JavaScript
Next, we'll use jQuery to listen for touch events on the elements we want to make hoverable.
<code class="javascript">$(document).ready(function() {
$('.hover').on('touchstart touchend', function(e) {
e.preventDefault();
$(this).toggleClass('hover_effect');
});
});</code>
This script ensures that when a touch starts or ends on an element with the "hover" class, the "hover_effect" class is toggled, effectively simulating the hover state.
Step 3: Prevent Unwanted Browser Behaviors (Optional)
To enhance the user experience, add this CSS snippet to prevent the browser from displaying menus or prompts related to copying or selecting the element:
<code class="css">.hover {
-webkit-user-select: none;
-webkit-touch-callout: none;
}</code>
And there you have it! By modifying the CSS and implementing a simple JavaScript script, you can seamlessly trigger hover effects on touch screens, giving your users a consistent and intuitive experience across all devices.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
